Marsh rainbow arch bridges in Iowa, 1997

The Marsh Rainbow Arch Bridge is a patented bridge design by James Barney Marsh, a graduate of Iowa State College of Agriculture and Mechanic Arts (now Iowa State University). Around the turn of the 20th Century, reinforced concrete was introduced in Iowa as an important new bridge construction material. Marsh used the new technology to encased steel truss arches in concrete to produce a sturdy yet esthetic arch bridge. This booklet touches on the important aspects of Marsh's life, business and industrial contributions.
